Throwing events in track and field are among the oldest sporting events in recorded history and include shot put, discus, hammer, and javelin. All throwing athletes use the kinetic chain to transfer energy from the lower extremities, through the pelvis, trunk, shoulder, arm, wrist, hand, and finally into the implement to generate maximum force. Throughout this sequential activation, mobilization, and stabilization of body segments, there is opportunity for breakdown in the chain, which can lead to injury. This review describes the biomechanics and kinetic chain components of each event and highlights injuries common among all throwers as well as injuries unique to each event. The cornerstone of prevention is practicing and competing with proper technique. It is important to understand the breadth of injuries that can affect these athletes to develop evidence based diagnosis, treatment, and prevention strategies.

Adaptive deep brain stimulation (DBS) provides individualized therapy for people with Parkinson's disease (PWP) by adjusting the stimulation in real-time using neural signals that reflect their motor state. Current algorithms, however, utilize condensed and manually selected neural features which may result in a less robust and biased therapy. In this study, we propose Neural-to-Gait Neural network (N2GNet), a novel deep learning-based regression model capable of tracking real-time gait performance from subthalamic nucleus local field potentials (STN LFPs).

The chiral lattice structure of twisted bilayer graphene with D_{6} symmetry allows for intrinsic photogalvanic effects only at off-normal incidence, while additional extrinsic effects are known to be induced by a substrate or a gate potential. In this Letter, we first compute the intrinsic effects and show they reverse sign at the magic angle, revealing a band inversion at the Γ point. We next consider different extrinsic effects, showing how they can be used to track the strengths of the substrate coupling or electric displacement field.

Background: The entorhinal cortex and hippocampus are loci of early vulnerability in AD. These areas are crucial for episodic memory processing for space and contexts. The majority of AD model mouse imaging and electrode studies utilize simple tasks such open field and linear track.
